This report documents a full-scale crash test conducted in support of a study to investigate the performance of New Jersey Department of Transportations (NJDOTs) Precast Concrete Curb, Construction Barrier, which will be referred as portable concrete barrier (PCB) in various configurations. This represents the third system as part of this study. The primary objective of this research effort was to evaluate the safety performance of the NJDOT PCB, Type 4 (Alternative B) with a free-standing configuration, corresponding to joint class A in the 2013 NJDOT Roadway Design Manual and connection type A in the 2015 NJDOT Roadway Design Manual. Barrier nos. 1 and 10 were anchored to a concrete tarmac through the pin anchor recesses with nine 1-in. (25-mm) diameter by 15-in. (381-mm) long ASTM A36 steel pins inserted into 1-in. (32-mm) diameter drilled holes in the concrete tarmac. The barrier was evaluated according to the Test Level 3 (TL-3) criteria set forth in the Manual for Assessing Safety Hardware (MASH 2009). The research study included one full-scale vehicle crash test with a 2270P pickup truck. Following the successful redirection of the pickup truck, the safety performance of the system was determined to be acceptable according to the test designation no. 3-11 evaluation criteria specified in MASH 2009. The 1100C small car crash test was deemed unnecessary due to previous testing. The barrier successfully met MASH 2009 TL-3 criteria. This report is the third of nine documents in the nine-test series.
